Specification of Letters Patent.

E'atented Nova 28, iii-i2,

Application filed June 22, 1912. Serial No. 705,231.

To all whom it may concern:

Be it known that I, FRED O. ANDERSON, a citizen of the United States, residing at Hamlin, in the county of Audubon, State of Iowa, have invented certain new and useful Improvements in Drum-Players; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to musical inst-ruments and has for an object to provide a snare drum player that may be manually controlled to produce, any desired number of staccato taps on the drum.

A further object of the invention is to provide an electrically actuated device of the class described that will have an adjustable clamp for attaching the device to various types of drums.

With the above objects in view the invention consists of certain novel details of construction and combination of parts herein-.

after fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claims.

In the accompanying drawing forming part of this specification :-Figure 1 is a side elevation of the device in applied position. Fig. 2 is a face view. Fig. 3 is an edge view. Fig. 4 is an end elevation, partly in section. Fig. 5 is a cross sectional view taken on the line 55 Fig. 2. Fig. 6 is a detail perspective view of the circuit closer.

Referring now to the drawing in which like characters of reference designate similar parts, 10 designates a snare drum and 11 the supporting stand thereof, these vparts being of ordinary construction and forming no part of the present invention.

The drum playing device comprises a substantially oblong back plate 12 having a rearwardly extending integral arm 13 disposed centrally on the rear edge, the arm terminatin in an internally threaded eye 14, throug which and a smooth bore eye 15 formed on the upper end of a bracket 16, a screw 17-is passed, both of the eyes'being clamped together between the head 18 and retaining thumb nut 19 of the screw. The bracket is provided at the lower end with an integral attaching lip 20, and is further provided with a hinged attaching lip 21,

the latter being bifurcated at the upper end to receive the bracket, and a pivot pin22 being passed through the parts to pivotally attach the lip. A clamp screw 23 is threaded through both lips and serves to draw the lips tightagainst the rim of the snare drum. By proper manipulation of the clamp screw the clamp lips may be adjusted to receive rims of various thicknesses.

Arranged on one face of the back plate is a vibratory tapper mechanism similar to that employed in ordinary buzzers, electric bells, etc, and including a pair of electromagnets 24, there being a vibratory armature 25 arranged across the cores of the magnets, this armature being provided at one end with a ball tapper 26, and being provided near the opposite ends with a trunnion. 27 which is journaled in the back plate and in a set screw 28 carried by a bracket 29 formed integral with the back plate. A helical spring 30 is attached to the armature on the opposite side of the trunnion from the ball tapper and to a lug 31 carried by the back plate and holds the armature on the same side of the trunnion as the tapper normally out of engagement with the magnet cores. A leaf spring 32 is secured at one end to the rear side of the armature and bears with its free end against an adjusting screw 33 carried by a lug 34 formed integral with the back plate.

For energizing the magnet I provide a pair of battery cells 35, a conductor wire 36 being led from one of the poles of one cell to corresponding binding post 37 carried by the back plate and connected electrically by a conductor wire 38 to one of the magnets. A conductor wire 39 is connected to one of the poles of the mating cell and is connect-- ed to a corresponding binding post 40 can ried by the back plate and connected electrically by a conductor wire 41 to the other of the magnets. The continuity of the conductor wire 39 is interrupted by a circuit closer which will now be described.

The circuit closer comprises a base plate 42 adapted to be secured to the floor or other suitable support, and having an up turned rear end 43 serving as a stop to pre' vent slippingoff of the operators heel. A treadle 44"is hinged at the rear end to the base plate in advance of the stop 43 as shown at 45. Secured to theconfronting faces of the treadle and base plate are metal contact points 46 and 47 to which the severed ends of the wire 39 are connected.- A helical spring 48 is interposed between the confronting faces of the treadle and base plate and serves to hold the treadle normally raised and contact points separated. Upon depression of the treadle by the 0perators foot, the contact oints will be brought into contact, and a circuit may then be traced from the battery cells through the circuit closer, electromagnets, and returning to the battery cells, and upon this circult being closed for a predetermined length of time the tapper will be continuously actuated during the period the circuit is closed.

. What is claimed, is

1. A'drum player including an electrically actuated drum tapping mechanism, a supporting back plate therefor having an integral arm provided with a terminal eye, a bracket having an eye in register with said drum eye, a screw engaged through both of said eyes, a nut on said screw serving to clamp both of said eyes against the head of said screw, said bracket being provided at the lower ends with an integral attaching lip, a hinged attaching lip on said bracket adapted to coact with said integral a lip in securing said bracket to a drum rim, a draw screw threaded through both of said lips and serving to draw said lips into clamping engagement with the drum rim, and controlling means for said tapping mechanism.

2. A drum player including an electrically controlled vibratory drum tapping device, and a circuit closer for said tapping device including a base plate having an upstanding heel stop, a treadle hinged to said base plate in advance of said stop, a spring interposed between said treadle and said base plate serving to hold said treadle in raised position, and contact points in circuit with said tapping device and disposed on said base plate and said treadle, and adapted to contact upon depression of said treadle against the tension of said spring.

In testimony whereof, I afiix my signature, in presence of two witnesses.
